Optical Centrifuge Superrotors

Using corkscrew-shaped laser pulses, scientists at DESY have devised a sophisticated optical centrifuge that can make molecules rotate rapidly about a desired molecular axis. [30] Neutron diffraction strain scanning measurements at ANSTO have validated a new theoretical model that successfully predicts the residual stresses and critical deposition heights for laser additive manufacturing. [29] Tensorial neutron tomography promises new insights into superconductors, battery electrodes and other energy-related materials. [28] CERN's nuclear physics facility, ISOLDE, has minted a new coin in its impressive collection of isotopes. [27] In the case of several light nuclei, experimental confirmation of the individualism or family nature of nucleons will now be simpler, thanks to predictions presented by Polish physicists from Cracow and Kielce. [26] The identification of the magic number of six provides an avenue to investigate the origin of spin–orbit splittings in atomic nuclei. [25] Now, physicists are working toward getting their first CT scans of the inner workings of the nucleus. [24] The process of the sticking together of quarks, called hadronisation, is still poorly understood. [23] In experimental campaigns using the OMEGA EP laser at (MIT) researchers took radiographs of the shock front, similar to the X-ray radiology in hospitals with protons instead of X-rays. [22] Researchers generate proton beams using a combination of nanoparticles and laser light. [21] Devices based on light, rather than electrons, could revolutionize the speed and security of our future computers. However, one of the major challenges in today's physics is the design of photonic devices, able to transport and switch light through circuits in a stable way. [20] Researchers characterize the rotational jiggling of an optically levitated nanoparticle, showing how this motion could be cooled to its quantum ground state. [19]
